Hillary Clinton had about two million more votes than Trump, the website notes. Trump has offered no details to support his claim millions of Clinton supporters voted illegally.

However, in the end it did not matter. Trump pulled in 306 electoral votes allowing him to claim victory in the bitterly contested race.

Some Democrats — and Krugman — are blaming FBI Director James Comey for reopening an investigation into Clinton's private email server about two weeks before the election. Just days before the election he once again cleared her saying he had not found any new evidence.

And there has been speculation in the Democratic ranks that Russian President Vladimir Putin's government may have hacked into some election results in close states and swayed the vote in favor of Trump even though there is no hard evidence to support this.

Green Party presidential candidate Jill Stein has already filed for a recount in Wisconsin and is pushing for more.
